3 Overview What is JCA? JCA 1.6 IronJacamar

4 What is JCA?

5 What is JCA? The Java Connector Architecture (JCA) standard specifies how the Java Enterprise Edition platform connects to Enterprise Information Systems (EIS) Database systems Messaging system Mainframe transaction processing Standard is created in JCP

6 What is JCA? JCA defines the contract between the JCA container and the EIS Scalable, Transactional, Secure, Client API Resource Adapter (EIS vendors) Protocol specific communication Multiple AS vendors Resource Adapter (AS vendors) Support multiple EISs

7 What is JCA? Resource adapters can be divided into Outbound, Inbound and Bidirectional Transactions NoTransaction, LocalTransaction, XATransaction Security javax.security.auth.subject

8 What is JCA? Examples JDBC resource adapter (outbound) Wraps JDBC API and adds connection pooling Timer resource adapter (inbound) Enables Quartz to invoke MessageEndpoints JMS resource adapter (bidirectional) Wraps JMS API (outbound part) Enables message invocation on MDBs (inbound)

9 Java Connector Architecture 1.6 JSR-322

10 JCA 1.6 Developed in JCP Sun (Spec lead), Red Hat, Oracle, IBM Ericsson, SAP, Tmax Focus on 4 key areas Ease of Development Generic Work context Security Inflow Misc enhancements

11 JCA 1.6 Ease of Development Make use Make META-INF/ra.xml optional Sparse metadata Better defaults

12 JCA 1.6 Generic Work Context (Message delivery / Work submission) WorkContextProvider TransactionContext, SecurityContext, HintsContext interface WorkContextProvider List<WorkContext> getworkcontextproviders(); interface WorkContext String getname(); String getdescription();

13 JCA 1.6 Security Inflow End-to-end security model Message delivery Work processing Uses JSR-196: Java Authentication Service Provider Interface for Containers JSR-196 Callback's used for establish caller identity

14 JCA 1.6 Misc enhancements Transaction support at run-time Distributed work Message endpoint timeouts Retryable exceptions Classloading Bean validation (JSR-303) public class MyResourceAdapterImpl @Size(min=5, max=5) private String myproperty;

15 JCA 1.6 Standalone environment Defines a JCA environment outside of an application server Focus on outbound communication inbound is optional Includes transactions, security and bean validation Up to vendor to choose the rest, like application component model

17 IronJacamar The IronJacamar project implements the JCA 1.6 specification Three modes of operation Standalone (JCA 1.6 Chapter 3.5) Embedded Inside JBoss Application Server 7

18 IronJacamar POJO based architecture Light-weight Fast Depends on frameworks also used in JBoss Application Server Supports two POJO kernels Standalone / Embedded: Fungal Inside JBoss AS 7: JBoss MSC

19 IronJacamar Configuration done through XML files Thread pools WorkManager BootstrapContext Deployer chain Setup different environments for the resource adapters Bind a RA to a BootstrapContext through jboss-ra.xml

20 IronJacamar <!-- RA deployer --> <bean name="radeployer" interface="com.github.fungal.spi.deployers.deployer" class="org.jboss.jca.deployers.fungal.radeployer"> <property name="archivevalidation">true</property> <property name="archivevalidationfailonwarn">false</property> <property name="archivevalidationfailonerror">true</property> <property name="beanvalidation">true</property> <property name="printstream"> <inject bean="jbossstdiocontext" property="out"/> </property> <property name="defaultbootstrapcontext"> <inject bean="defaultbootstrapcontext"/> </property> <property name= TransactionManager > <inject bean= RealTransactionManager /> </property> <depends>beanvalidation</depends> <depends>jbossstdiocontextselector</depends> </bean>

21 IronJacamar Standalone environment Kernel: Fungal Logging: JBoss Logging + JBoss Stdio Naming: JBoss Naming Threads: JBoss Threads Bean validation: Hibernate Validator Transactions: JBoss TS Security: JBoss Security Web: Jetty

22 IronJacamar Embedded use-cases Embed a JCA container inside an application Easy unit testing of resource adapters Embedded container Running In-VM Built on standalone functionality As easy as possible Integration with ShrinkWrap and Arquillian

23 IronJacamar Tools: Validator Help resource adapter developers make their implementation spec compliant Validates resource adapter against rules defined in the specification ResourceAdapter, ManagedConnectionFactory, ManagedConnection,... Deployer, Standalone, Ant, Maven

24 IronJacamar Tools: Code Generator Help resource adapter developers get started Generates code skeleton for JCA 1.0, JCA 1.5, JCA 1.6 Based on user input / configuration Provide implementation hints

25 Enough already! DEMO TIME

26 The future Enterprise level features Optional parts of the specification f.ex. DistributedWorkManager OSGi/JCA More focus on usability especially embedded Tools / Samples

27 Last thoughts JCA 1.6 adds key areas to the specification Included in the full profile of Java Enterprise Edition 6 The IronJacamar standalone / embedded distribution provides a way to get started today
